You also need the leap records to determine the magnitude of the tm_sec field during leaps (see the "hit" variable, which probably shouldn't be a bool BTW).
I think the question was the opposite - not why the leap records exist, but why they're not the _only_ difference between a leap tzfile and a non-leap one.
